Employer Drug Testing Framework

A concise, workflow-oriented reference for structuring pre-employment, post-accident, reasonable suspicion, and random drug testing programs.

1. Pre-Employment Testing

• Timing: Conduct urine or saliva screening before any final job offer or start date.
• Authorization: HR or the hiring manager authorizes testing upon conditional offer.
• Method: Use instant test kits (urine cups, saliva devices, or dip cards) consistent with policy; THC panel is optional where excluded by region or job role.
• Documentation: Record collection time, date, collector name, and applicant acknowledgment.
• Retention: Securely store results and the Chain of Custody Form for a minimum of one year, or per company policy.
• Confirmation: Non-negative results are confirmed through a secondary laboratory test or MRO review, if required.

2. Post-Accident Testing

• Timing: Triggered immediately after any workplace incident involving injury, property damage, or a near miss where impairment is suspected.
• Authorization: The Safety Manager or on-duty supervisor authorizes testing.
• Method: Collect as soon as feasible; saliva or instant urine kits are preferred for rapid insight.
• Documentation: Record incident details (time, witnesses, conditions) alongside collection documentation.
• Retention: Maintain results with the accident report for regulatory and insurance compliance.
• Confirmation: Confirm non-negative or disputed results through the lab or MRO process.

3. Reasonable Suspicion Testing

• Trigger: Initiated when a trained supervisor observes clear signs of possible impairment (odor, behavior, speech, coordination).
• Authorization: Must be approved by HR or a designated manager prior to testing.
• Method: Conduct an on-site instant test using a saliva or urine method for timeliness.
• Documentation: The supervisor completes a Reasonable Suspicion Observation Form before collection.
• Safety: Ensure the employee is transported safely and is not allowed to return to duty pending results.
• Retention: Document and store findings securely to support defensible action.

4. Random Testing

• Selection: Conducted under a documented, randomized selection process (software or third-party draw).
• Scope: Applicable to all safety-sensitive or covered employees.
• Coordination: The supervisor receives the authorized test list and coordinates unannounced collections within the testing window.
• Method: Use urine or saliva kits appropriate to job type and shift logistics.
• Retention: Keep selection logs, testing dates, and results confidential but audit-ready.
• Outcomes: Any positive or refused tests are handled per the company's disciplinary and retest policy.
